• Does the mail piece meet aspect ratio requirements for automation letter rates? (width\height = 1.3 to 2.5)

• Does paper color allow enough contrast for bar code to work? (darker blues, greens and reds especially cause problems)

• Will final dimensions be less than 6.125″ tall and 11.5″ wide? (outside either will bump you into higher postage)

• Will finished piece be less than 3.5 ounces and less than .25″ thick? (if heavier or thicker, higher postage and processing rates will apply).

• If not using offset stock will the coated stock used accept ink without smearing? (most types are okay but if in doubt samples should be run).

• If a 1 page self-mailer are you using at least 28#/70# paper? (minimum required for automation).

• If multiple pages, is paper used at least 24#?

• Will staples be used in the binding of your mail piece?  This likely will mean it’s a booklet and will require booklet tabbing.

• If a postcard, is it at least 3.5″ x 5″ and no more than 4.25″ x 6″? (stock must be at least 7pt. finished, if larger, then 9pt. finished)

• If a reply piece is included, does it have a FIM code and the correct address bar code? (artwork to be obtained from the USPS)
